    request.session.delete()

    return redirect('/login/')


def index(request):
    return render(request,'index.html')

添加路由

from django.contrib import admin
from django.urls import path
from stark.service.v1 import site
from web.views import account
urlpatterns = [
    path('admin/', admin.site.urls),
    path('stark/', site.urls),
    path('login/', account.login, name='login'),
    path('logout/', account.logout, name='logout'),
    path('index/', account.index, name='index'),
]

添加登录和首页模板

login.html

{% load static %}



    
    
    



    

        {% csrf_token %}
        

            用户名
            

                
            
        
        

            密码
            

                
            
        
        

            

                

                    
                         记住密码
                    
                
            
        
        

            

                登 录
                {{ msg }}
            
        
    

index.html

{% extends 'layout.html' %}

{% block content %}
    

        
欢迎使用
    
{% endblock %}
